Select Water Cement Ratio = 0.43 for concrete grade M35 (From Fig 2. of I.S. 10262- 1982) Select Water Content = 172 Kg (From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M 3) Hence, Cement Content= 172 / 0.43 = 400 Kg / M 3
More Details· Concrete is a composite of gravel or crushed stone (coarse aggregate), sand (fine aggregate), and hydrated cement (binder) and gives the mixture considerable hardness. The cement reacts chemically with the water and other constituents to form a hard matrix that binds all materials together into a durable, stone-like material with many uses.

More Details· But the key is to ensure that the M-sand is procured from a reliable source and should be adequately processed. When the concrete mix (1:1.82:2.96) of grade M20 was tested for replacing the river sand with M-sand, the concrete mix was found to have better strength and durability when it was compared with river sand.
More DetailsOne reason it is used as a backfill or sub-grade material. As with all material, it has to be placed correctly and compacted properly. Sand needs to remain damp as well as other material before placement of the concrete. If you want to build a road, use gravel, but this does not mean you will not have issues.
More Details· The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes. This principles works in the opposite direction as well. If you want to get a little more technical, some concrete experts recommend going for 26 percent sand, 41 percent gravel, 11 percent cement and 16 percent water.
